Grass Bag Cleaning And Replacement; Spark Arrester Service - Honda HRX537HXEA Owner's Manual

Blade Removal
1. HXEA: Put the throttle lever in the STOP position.
HMEA: Turn the key to the OFF position.
2. Turn the fuel valve OFF. Disconnect the spark plug cap, then tilt
the mower to the right side, so the air cleaner side is up. This will
help to prevent fuel leakage and hard starting due to carburetor
flooding.

3. Use a 14 mm (6 point) socket wrench and remove the two blade
bolts [1] and special washers [2] from the blade control assembly
[5]. Use a wooden block to prevent the blades from turning when
removing the bolts.
4. Remove the upper [4] and lower blades [3].
Blade Installation
1. Clean dirt and grass from around the blade mounting area. Install
the blades [3] and [4] using the two blade bolts [1] and special
washers [2] as shown.
[6]
[7]
Be sure to install the special washers with the concave side toward
the blades and the convex side toward the head of the bolt.
The blade bolts are specially designed for this application and
must not be replaced with other bolts.
2. Tighten the blade bolts with a torque wrench [7]. Use a wooden
block [6] to prevent the blades from turning.
Blade bolt torque: 49 ~ 59 N·m
If you do not have a torque wrench, have an authorized Honda
dealer tighten the blade bolts before you use the mower. If the
blade bolts are overtightened, they could break. If the blade bolts
are not tightened enough, they could loosen or come out. In either
case, it would be possible for the blades to fly off while you are
operating the mower.
